This article reviews new scholarship on lesbian, gay, bisexual, and transgender families. The past decade witnessed rapid expansion of data and strong research designs. The most notable advance was in studies on variation among mostly planned lesbian comother families. Cumulative evidence suggests that although many of these families have comparatively high levels of shared labor and parental investment, they may not be as "genderless" as previously depicted. Gay men's diverse paths to family formation and planned parenthood have also been explored, but almost no research studies their children's experiences. Conceptualizations of sexual orientation expanded to include bisexuals and others, and some understanding of the experiences of transgender people has begun to emerge. Future work should explore relationships among members of the families they create.
